what is One less than the quotient of four and a number x

Question

i need help on khanacademy please

Answer 1

4/x -1

quotient of 4 and a number means 4 is the dividend and "a number" is the divisor

quotient is 4/x. what you get when you divide x into 4

one less means 4/x - 1

It might be easier to see what's going on using a specific number for x, such as x=2

then 4/2 -1 = 2-1 = 1

quotient of 4 and 2 is 4/2 = 2

one less is 2-1 = 1
